DollaTek PWM Signal Generator Pulse Frequency Duty Cycle Adjustment Module Adjustable Square Wave Rectangular Wave Signal Source
Description:3-way PWM output, wide frequency range, duty cycle can be adjusted independently and in real time.Frequency is divided into four ranges, automatic switching:1. XXX (no decimal point): the smallest unit is 1Hz, the range of values is 1Hz ~ 999Hz;2. The smallest unit of X.XX (decimal point in 100 bits) is 0.01 Khz, ranging from 1.00 Khz to 9.99 Khz.3. XX.X (decimal point in ten places): the smallest unit is 0.1Khz; the range of values is 10.0KHz~99.9KHz.4. X.X.X (decimal point in 10 and 100 bits): the smallest unit is 1Khz; the range of values is 1KHz~150KHz Features:Square wave signal used to control motor driver;Generate adjustable pulses for MCU use.Generate adjustable pulses and control related circuits (PWM dimming and speed regulating applications).The module has 8 independent keys to set the frequency and duty cycle. It supports short press (increase or decrease a unit) and long press (increase or decrease quickly). It is very simple. After setting parameters, it can save automatically without losing power. 3-way duty cycle button can be pressed at the same time, real-time adjustment, LCD display is the last pressed button duty cycle, real-time performance is very strong, can be used as a simple scan of several ways duty cycle. Specification:Working voltage: 3.3-30VFrequency range: 1Hz~150KHzFrequency accuracy: the accuracy in each range is about 2%Signal load capacity: the output current can be about 5-30 maOutput amplitude: PWM amplitude is equal to supply voltageAmbient temperature: - 20°~ + 70°C Package included:1 x Controller Module
